Low light conditions refer to environments with minimal illumination, which can challenge visual perception and activities.

The Pupil

The adjustable opening in the center of the eye through which light enters, its size regulates the amount of light that reaches the retina.

Retina

The light-sensitive layer of tissue at the back of the inner eye which converts light images into electrical signals sent to the brain via the optic nerve.
